4 Application filed July 30,1896. Serial No. 601,028. (No model.)

o alt 'LU/tom, t may concern:

Haverhill, county of Essex, Stateof Massachusetts, have invented anImprovement in Skivingddachines, o f which the following description, inconnection with the accompanyparts. i

This invention has for its object the pr'oduction of a novelskiving-machine more especially adapted to skive heel-lifts orspringholder which may be turned more or less in or on a circular seat,so that the inclination Y ofthe bevel to be cut may be readily changed.

Figure l, in front elevation, represents a skiving-machine embodying myinvention; Fig. 2, a left-hand side elevation thereof; Fig. 3, a partialsection in the line no, Fig. 2; and Figs. 4t and 5 showthe cutting endsof the blades or knives which my machine. Fig. 6 shows the gage a andpart of the table, and Fig. 7 shows aheellift with its end skived.

The framework A has at one side a projecting hub 2, (shown in Fig.` 1,)which receives a stud on which turns the sleeve of pulley A2, saidsleeve nhaving a pinion A3,

(shown `by dotted lines,) which engages a larger toothed gear A4, fastonlthe end of a shaft B, extended through a hollow sleevelike bearing Bat the upper end of a plate B2, xed to the frame A by suitable bolts B3,the left-hand-A end of 1 said shaft carrying a feed-roll B4, which isrotated at speed. The stud on which the fast pulley rotates is extendedfar enough to also sustain a loose pulley A5, itbeing kept from slippingolf the end of said stud in any usual way.

The shaft B has a pinion B5, which engages a pinion C of Ycorrespondingsize on andV rotates a shaft C', having a second feed-roll CX, saidshaft lying in a hollow tube-bearing C2 at the outer end of a lever C3,mounted on a rod C, sustained by ears C5 of the bed, the outer end ofsaid lever being acted upon by a strong spring D, made adjustable as toits ing drawings, is a specification, like lettersl and iigures on thedrawin gs representing like? may bel used in- D 1 strengthpsaid springacting to keep the pin- Be 1t known that I, JAMES N. MOULTON, ofl

ionsKB5 and C in engagement, yet allowing Athem to yield slightly, `yetkeep a firm bight on the piece of l`eatlie1bein g passed between them tobe sk ived, the approach of the rolls toward eachother being adjusted byan adjusting-device D',s hown as a screw carried by the lever C3. l

The front of the machine has attached to .it by suitable bolts D2 atable D3, on which is laid the leather or material to be skived, said ftable having on its surface suitable adjust able edge guides ct a', theface of the righthand gage shown inhig. G vbeing beveled inwardly towardthe face of the gage a, so as or knife having its front end beveledwholly at one side, as in Fig; 4, or on both sides,ias

shown Vin Fig. 5, according to the work to be` done.

The shank `of the blade or knife is slotted, as shown' inFig. 2, toreceive screws b', said screws'connecting said blade adjustably to aholder 52 having one side rounded and set in a seat 193,-aset-sc1ew b4,connected to said holder and extended through a slot inthe seat,enabling the said holder to be turned in a circular path to therebychange the inclination of the front cutting edge of the blade or knifewith relation to the Vsurface of the table to chan ge the bevel of thescarf or skived edge to be made by the blade or knife.

The machine has a counting mechanism to indicate the number of skivingcuts made on the machine, said counting mechanism having usual gearing',which will move the marked disks to indicate the number, the gearingbeing contained in a box d, said box having attached to its rear side apawl-carrier having a suitable pawl CW, which engages one of theratchet-Wheels of the train of gearing in the box, said pawl havingconnected to it a link cl2, the opposite end of said link being jointedVto an arxn d3, fast on a rock-shaft d4, having fast on its lower end acam-shaped IOO arm d5, which is struck by each lift or piece of leatherwhich is y"fed between the rolls, thc action of the 4leather on thelever moving it to actuate the pawl carrier d', a suitable spiral springd6,conn ected to said pawl-carrier and to a fixed stud d?, actingnormally to hold the saidarin d5 in the path of movement of the leatherbeing skived.

The seat b3 for the holder is shown as a lip projecting laterally fromthe upper end of a plate e, slotted for the reception of aclamping-screw c4, by which to hold the plate Yin position, said plate,when the screw is loosened, being made adjustable by adjustingscrews e.,held in a rib e2 of the frame., a screw e3 acting as a stop-screw torelieve strain on the screw el.

The heel-lifts to be skived at their breast ends are usually employed-in spring-heeled shoes, and they are composed of one-or more layers ofleather suitably pasted together. One `of these heel-lifts is yshown inFig. 7.

When a heel-blank-of Vsuitable size for-one heel is to be beveled, theblade'shown in Fig. 4, it having one bevel, Will be used; but if theblank is long enough for two lifts -then it will be out centrallybetween its lends and the blade will have two bevels, as shown in One ofthe Vfeed-rolls is provided with a deep annular V-shaped groove of suchdepth as to enable the sharp front inclined edge of the blade to enterand act on the leather to be out close to the line in which the leatheris nipped by the feed-rolls.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The `combination with feeding mechanism of a skiving-machine, of a bladeor knife, a holder therefor, a scat to receive said holder, a .plate towhich said seat is secured, ka horizontal rib on the frame of themachine, and independent adjusting means at opposite ends of said ribengaging said plate, substantially as described.
